I Sverige tillverkas betong normalt med glaciofluviala grusavlagringar(naturgrus). På senare år har tillgång på naturgrus blivit starkt begränsade i vissa regioner och man vill av miljöskäl minska förbrukningen av det som återstår. Återvinnig av material som kan ersätta detta är både bra av miljöaspekt samt öppnar väg för produktion av betong med nya egenskaper.Med lättballastbetong avses betong i vilken ballastmaterialet helt eller delvis består av någon typ av lättballast som har en partikeldensitet som är markant mindre än vad som är normalt för normala bergartsmaterial såsom granit, gnejs eller kalksten. Lättballast är porös, dvs innehåller hålrum, och får därför lägre hållfasthet än normalballast. I lättballastbetong bestämmer lättballastpartiklarna många av betongens egenskaper, såsom hållfasthet, elasticitetsmodul och krympning.Examensarbetets inledande del är en state-of-the-art rapport som omfattar tillverkning av lättballastbetong i allmänhet, både i färsk och hårdnade tillstånd, samt dess beståndsdelar med fokus på skumglas som lättballast.

The purpose of this thesis is to examine if the school's democracy project is successful. The objective is examined in relation to two specific questions. The first question is whether students, after completing their studies in civics A, understand the relationship between the concepts of human rights and democracy. The second is if the students understood the concepts of practical significance and impact on society and the individual. Variation theory comes from the phenomenographic theories and is central to this work. The approach to learning, in this essay, is a change in how a person experiences, understands or perceives a phenomenon. Variation theory focuses on a learning object and contextualization sees as crucial to how the individual perceives the object.The study is based on a quantitative research method in the form of a survey at a secondary school. A number of students may respond to valuation questions about how they perceive democracy and human rights in practical situations. The results are related to curriculum goals.The results of the study is not positive in relation to curriculum objectives, where many students respond negatively to questions..

This bachelor thesis, written as a part of the European Studies at Gothenburg University, is concerned with the European Unions? (EU) climate political governance in their both climate- and agricultural policy, and in particularly the question whether it is sustainable. This thesis intends to problematize if it is possible for the EU to continue to pursue its current agricultural policies, while at the sametime maintain its role as a sustainable actor on the global arena. The framework of theEUs? climate policy governance disciplines this analysis.

The study is based on the pragmatic question whether one can apply the theoretical perspectives priming, experience space and relationship marketing in a practical context. The authors visualize how these concepts appear practical and what advantages and disadvantages can be discerned in the particular case of HV71. The method used is a hypothetico-deductive approach, which is not entirely conventional in the humanistic and social scientific context. Consequently, it has been proven to be particularly suitable as it could expose the theoretical perspectives for a difficult scientific test.The result of the study demonstrated that a marketer could benefit from using the theoretical perspectives when exercising the profession. It also showed that the object of study applied these perspectives.

This essay aims to investigate how students in upper secondary school perceive the subject religion A. The study is both qualitative and quantitative and I will use a survey to investigate the perception of religion among students both vocationally oriented and theory oriented. I will use questions concerning religious background and perception on the subject in relation to the curriculum but also try to investigate whether there are differences on perception between the vocational and theory orientation. The theoretical approach is mainly based on the curriculum concerning religion A but former research is also used such as books written by Sven G Hartman (2000), Ulf Sjödin (1995), Ove Larsson (1991), Elsie Davidsson (1989) and Anders Törnwall (1988). The result in the study is that students for the most part perceive the subject religion A as something positive and the background has a connection to their present perception.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

This master thesis focuses mainly on the concept of quality and how the librarians responsible for phonogram purchase use it. The main object is to investigate how the librarians responsible for the purchasing of phonogram works when in the process of selecting the phonograms and how they speak about the concept of quality. Based on this main object four problems has been addressed. The empirical material is interviews made with the seven librarians responsible for phonogram purchase at seven Swedish libraries. The result of this investigation is analyzed based on a theoretical framework created by Sanna Talja, which focuses on what a phonogram collection should contain.

Social enterprises make up one of the groups of participants that provide welfare services financed by public funding. The object of this study is to describe and analyze from a theoretical point of view which conditions, in what fields, by which division of responsibility and finally through what decisions these social enterprises are allocated a place in the market for social welfare services. The company that has been the object of study offers services in the field of social welfare and in employment. In the study a triangulation of qualitative methods has been used: studies of literature on the subject, recurrent interviews and observations and also reviews of documents. The results have been analyzed from theories on the space available on the market for social services, on social economy and on social capital in the form of strong, weak and bridging bonds.

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

How can the object based art help us, as viewers and as makers, to access a supplanted emotional state?One way of positioning yourself within the corpus-field is to step outside the traditional borders of the field and aim for other values within the objects, such as a visible working process, a storytelling or an emotional relationship to the object.  It is a way of taking a step from the traditional silversmithing towards some kind of free undefined corpus-art.  To reach for suppressed feelings is one way to find an importance within the artistic work, to give it a purpose.By investigating the concept of the sublime and the surrealist movement I try to find examples on how you, both as a viewer and as a maker, can put yourself in an emotional/intuitive state.  Through interviews with Jewellery and corpus artists I get a maker?s perspective which I compare with my own reactions to their work.Works of art can be used as a catalyst to reach, and maybe also to process, unattended feelings. This creates a strong emotional connection to the work.  As a maker you can, for example, do this by working with it as a theme, or by using an intuitive working method.

The purpose of this Master thesis is to illustrate the public librarian. People in general, including library users and leading personalities in the field of culture in the communities do not know the tasks of the public librarian. We presume that the vague picture of duties of the public librarian might cause problems. In this dissertation we mean to examine only public librarians, hereby we exclude for example, university- and company librarians. The sentences of this thesis are: How are the public librarians viewed, in meaning of, tasks, role/-s, comptetence/-s, status and image? And can we call it a "profession" in the classical sense? We answer these questions by using relevant literature, interviews and conference paper.

Neighbourhood offices were established in the municipal of Lund by a decision in the municipal council 1999. During following years four offices opened in the surrounding villages; Veberöd, Genarp, Södra Sandby and Dalby. By using a goal oriented model and making interviews I study whether the offices reaches the goals of more effective service, developed IT-support, a stronger local democracy and a better feeling for service. The offices has improved the information to the citizens and efforts have been made to strengthen the local democracy but more complex matters can not be handled at the offices today, which is a disappointment for many involved.To explain the result of the evaluation I use Vedungs ?A general theory of public efforts result?.

Abstract? ?there is no reason?to assume that prehistorians cannot study ancient symbolism and beliefs. The question remains, however, how best to study symbolism within the material confines of archaeological research?(Fogelin 2007:63)With my essay I would like to bring up the meaning of the soapstonelamp for the Thule culture in Greenland. Humans in the arctic area, from the same in the north of Scandinavia to the inuites in Greenland, have a common way of viewing the world that stems from anemismen.

In this thesis ? concerning didactics of literature ? I perform a reading and theoretical analysis of two pivotal works within reader-response theory, more precisely: Literature as Exploration (1938) and The Reader, the Text, the Poem ? The Transactional Theory of the Literary Work (1978), both written by Louise M. Rosenblatt. The object of this analysis is to examine whether Rosenblatts? theory and methodology can be used to accomplish understanding for ?the other?, what Martha C.
